i just replaced two of the toner cartridges (Cyan and Magenta) and once my printer re-sets itself, it no longer prints black toner and it seems to be caught in a cycle of cleaning the printhead over and over again. The device was working yesterday without issue and i have replaced the toner with genuine HP cartridges. All toner cartridges are full.
The printer does not display any error messages. When cleaning the printhead, it's now making a squeaking sound. Argh!
